Re: StefEbike for my wonderful disabled wife

Made it through with determination though. I think you had more than determination going for you! Living 1.5 blocks from the Mississippi, with lots of great trails along the river, I get lots of opportunities to do what you did. I'll tackle up-to-axle depths with a non-electric recumbent 'high race...

Re: Cycle Analyst V3 preview and first beta release

The short answer is "yes".

The long answer is that all the details you need to implement the above short answer are in this ES thread and the CAv3 manual, fully available online (link also in this thread). Happy reading!

Re: My recumbent cargo bike

Only a small part of it, but I think my hands get less cold in cold weather, better circulation. I hadn't even considered that, but since I do a lot of winter riding and have circulation issues, that might be another plus. My main concern is, as Warren so poetically suggests above, that you feel li...

Re: My recumbent cargo bike

I'm still looking for a chance to try USS -- all four of my recumbents have the over-seat-steering, almost entirely due to the fact that "they came that way". It's not that they're uncomfortable or don't handle well, but I've always 'assumed' that the view is better with the under-seat-steering, and...

Re: My recumbent cargo bike

Hey Warren -- nice travelogue! It looks like using more regen braking during your fog ride significantly improved your watt hours per mile. This matches nicely with my experience, but your 'sampling rate' of 100+ miles makes for better data. Nice top end speeds, btw -- that's the nice road hugging s...

Re: BionX, want help connecting up this motor

I could get a reading then when I flipped the magnet over the reading would go away. I did it several times. It seems to be working. It's the sensor's switching when magnetic poles transition that's the critical part. The absolute voltage levels may be due to other issues, such as using the wrong '...

Re: BionX, want help connecting up this motor

What does the hall sensor do? Does it send signal back so the speed controller knows what signal to send to the motor? The Hall sensors assist your controller in knowing the relative positions of the stator (non moving part, or the 'axle' assembly in the case of the BionX motor) and the rotor (the ...

Re: BionX, want help connecting up this motor

My experience with Hall sensors is that as long as you limit Vcc voltage to ~5VDC, you're not going to 'fry' the sensor. If the connections are wrong it just won't work. I couldn't find the data sheet for this particular sensor so I just identified the leads by trial and error. The test method I use...

Re: BionX, want help connecting up this motor

I have a question about the hall sensors. I had to cut them off the circuit board but they were not labeled. Does anyone know positive , negative, and signal? This is for a BionX Hall sensor "502A 4117", which is a digital switching/latching sensor. If looking at it so as to read the label printed ...

Re: BionX, want help connecting up this motor

As long as you don't have to run the wires along a route that gets flexed a lot, ethernet wire is perfect. There's almost no current going through this system, so even 30AWG would probably be enough, even on a 'longish' bike like yours. The high twist factor of even Cat3 ethernet will help reduce no...

I realize this "buy" is closed, but do you have these motors for sale out of your store's stock by any chance? I'd sent you an email at your website a week ago but haven't had a reply. Thanks!

Re: BionX: how to access bad strain gauge sensor?

Thanks for the update. Let's hope the freehub threads remain functional. I agree with your take on the BionX throttle -- it's very difficult to hold it in any particular position. I'm not sure this applies on your system, but on mine, just holding it WOT (wide open throttle) resulted in the bike goi...

Re: BionX: how to access bad strain gauge sensor?

I like your approach to toolmaking -- kudos to you for great ingenuity! May I assume that the freehub threads are standard/left hand threads? It looks like you have the newer, big 'pancake' hub motor, in which the part of the axle with the strain gauge appears to be even *outside* the motor's casing...

Re: Help Bionx battery bleeping when fully charged

Disconnect both the power (2 wire) and signal (multiple small wires) connectors from the motor and with the wheel off the ground, spin the wheel by hand. If the motor resists spinning with a "significant" amount of force, you likely have a short circuit in your phase supply system and would require ...
